4
5
6 Changes between 0.9.2b and 0.9.3
7
8 *) Add support for CRL distribution points extension. Add Certificate
9 Policies and CRL distribution points documentation.
10 [Steve Henson]
11
12 *) Move the autogenerated header file parts to crypto/opensslconf.h.
13 [Ulf Möller]
14
15 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
16 8 of keying material. Merlin has also confirmed interop with this fix
17 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
18 [Merlin Hughes <merlin@baltimore.ie>]
19
20 *) Fix lots of warnings.
21 [Richard Levitte <levitte@stacken.kth.se>]
22
23 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
24 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
25 [Richard Levitte <levitte@stacken.kth.se>]
26
27 *) Fix problems with sizeof(long) == 8.
28 [Andy Polyakov <appro@fy.chalmers.se>]
29
30 >>>>>>> 1.185
31 *) Change functions to ANSI C.
32 [Ulf Möller]
33
34 *) Fix typos in error codes.
35 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
36
37 *) Remove defunct assembler files from Configure.
38 [Ulf Möller]
39
40 *) SPARC v8 assembler BIGNUM implementation.
41 [Andy Polyakov <appro@fy.chalmers.se>]
42
43 *) Support for Certificate Policies extension: both print and set.
44 Various additions to support the r2i method this uses.
45 [Steve Henson]
46
47 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
48 return a const string when you are expecting an allocated buffer.
49 [Ben Laurie]
50
51 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
52 types DirectoryString and DisplayText.
53 [Steve Henson]
54
55 *) Add code to allow r2i extensions to access the configuration database,
56 add an LHASH database driver and add several ctx helper functions.
57 [Steve Henson]
58
59 *) Fix an evil bug in bn_expand2() which caused various BN functions to
60 fail when they extended the size of a BIGNUM.
61 [Steve Henson]
62
63 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
64 support typesafe stack.
65 [Steve Henson]
66
67 *) Fix typo in SSL_[gs]et_options().
68 [Nils Frostberg <nils@medcom.se>]
69
70 *) Delete various functions and files that belonged to the (now obsolete)
71 old X509V3 handling code.
72 [Steve Henson]
73
74 *) New Configure option "rsaref".
75 [Ulf Möller]
76
77 *) Don't auto-generate pem.h.
78 [Bodo Moeller]
79
80 *) Introduce type-safe ASN.1 SETs.
81 [Ben Laurie]
82
83 *) Introduce type-safe STACKs. This will almost certainly break lots of code
84 that links with OpenSSL (well at least cause lots of warnings), but fear
85 not: the conversion is trivial, and it eliminates loads of evil casts. A
86 few STACKed things have been converted already. Feel free to convert more.
87 In the fullness of time, I'll do away with the STACK type altogether.
88 [Ben Laurie]
89
90 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
91 specified in <certfile> by updating the entry in the index.txt file.
92 This way one no longer has to edit the index.txt file manually for
93 revoking a certificate. The -revoke option does the gory details now.
94 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
95
96 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
97 `-text' option at all and this way the `-noout -text' combination was
98 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
99 [Ralf S. Engelschall]
100
101 *) Make sure a corresponding plain text error message exists for the
102 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
103 verify callback function determined that a certificate was revoked.
104 [Ralf S. Engelschall]
105
106 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
107 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
108 all available cipers including rc5, which was forgotten until now.
109 In order to let the testing shell script know which algorithms
110 are available, a new (up to now undocumented) command
111 "openssl list-cipher-commands" is used.
112 [Bodo Moeller]
113
114 *) Bugfix: s_client occasionally would sleep in select() when
115 it should have checked SSL_pending() first.
116 [Bodo Moeller]
117
118 *) New functions DSA_do_sign and DSA_do_verify to provide access to
119 the raw DSA values prior to ASN.1 encoding.
120 [Ulf Möller]
121
122 *) Tweaks to Configure
123 Niels Poppe <niels@netbox.org>
124
125 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
126 yet...
127 [Steve Henson]
128
129 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
130 [Ulf Möller]
131
132 *) New config option to avoid instructions that are illegal on the 80386.
133 The default code is faster, but requires at least a 486.
134 [Ulf Möller]
135
136 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
137 SSL2_SERVER_VERSION (not used at all) macros, which are now the
138 same as SSL2_VERSION anyway.
139 [Bodo Moeller]
140
141 *) New "-showcerts" option for s_client.
142 [Bodo Moeller]
143
144 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
145 application. Various cleanups and fixes.
146 [Steve Henson]
147
148 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
149 modify error routines to work internally. Add error codes and PBE init
150 to library startup routines.
151 [Steve Henson]
152
153 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
154 packing functions to asn1 and evp. Changed function names and error
155 codes along the way.
156 [Steve Henson]
157
158 *) PKCS12 integration: and so it begins... First of several patches to
159 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
160 objects to objects.h
161 [Steve Henson]
162
163 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
164 and display support for Thawte strong extranet extension.
165 [Steve Henson]
166
167 *) Add LinuxPPC support.
168 [Jeff Dubrule <igor@pobox.org>]
169
170 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
171 bn_div_words in alpha.s.
172 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
173
174 *) Make sure the RSA OAEP test is skipped under -DRSAref because
175 OAEP isn't supported when OpenSSL is built with RSAref.
176 [Ulf Moeller <ulf@fitug.de>]
177
178 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
179 so they no longer are missing under -DNOPROTO.
180 [Soren S. Jorvang <soren@t.dk>]
181
182 Changes between 0.9.1c and 0.9.2b
183
184 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
185 doesn't work when the session is reused. Coming soon!
186 [Ben Laurie]
187
188 *) Fix a security hole, that allows sessions to be reused in the wrong
189 context thus bypassing client cert protection! All software that uses
190 client certs and session caches in multiple contexts NEEDS PATCHING to
191 allow session reuse! A fuller solution is in the works.
192 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
193
194 *) Some more source tree cleanups (removed obsolete files
195 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
196 permission on "config" script to be executable) and a fix for the INSTALL
197 document.
198 [Ulf Moeller <ulf@fitug.de>]
199
200 *) Remove some legacy and erroneous uses of malloc, free instead of
201 Malloc, Free.
202 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
203
204 *) Make rsa_oaep_test return non-zero on error.
205 [Ulf Moeller <ulf@fitug.de>]
206
207 *) Add support for native Solaris shared libraries. Configure
208 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
209 if someone would make that last step automatic.
210 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
211
212 *) ctx_size was not built with the right compiler during "make links". Fixed.
213 [Ben Laurie]
214
215 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
216 except NULL ciphers". This means the default cipher list will no longer
217 enable NULL ciphers. They need to be specifically enabled e.g. with
218 the string "DEFAULT:eNULL".
219 [Steve Henson]
220
221 *) Fix to RSA private encryption routines: if p < q then it would
222 occasionally produce an invalid result. This will only happen with
223 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
224 [Steve Henson]
225
226 *) Be less restrictive and allow also `perl util/perlpath.pl
227 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
228 because this way one can also use an interpreter named `perl5' (which is
229 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
230 installed as `perl').
231 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
232
233 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
234 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
235
236 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
237 advapi32.lib to Win32 build and change the pem test comparision
238 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
239 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
240 and crypto/des/ede_cbcm_enc.c.
241 [Steve Henson]
242
243 *) DES quad checksum was broken on big-endian architectures. Fixed.
244 [Ben Laurie]
245
246 *) Comment out two functions in bio.h that aren't implemented. Fix up the
247 Win32 test batch file so it (might) work again. The Win32 test batch file
248 is horrible: I feel ill....
249 [Steve Henson]
250
251 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
252 in e_os.h. Audit of header files to check ANSI and non ANSI
253 sections: 10 functions were absent from non ANSI section and not exported
254 from Windows DLLs. Fixed up libeay.num for new functions.
255 [Steve Henson]
256
257 *) Make `openssl version' output lines consistent.
258 [Ralf S. Engelschall]
259
260 *) Fix Win32 symbol export lists for BIO functions: Added
261 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
262 to ms/libeay{16,32}.def.
263 [Ralf S. Engelschall]
264
265 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
266 fine under Unix and passes some trivial tests I've now added. But the
267 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
268 added to make sure no one expects that this stuff really works in the
269 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
270 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
271 openssl_bio.xs.
272 [Ralf S. Engelschall]
273
274 *) Fix the generation of two part addresses in perl.
275 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
276
277 *) Add config entry for Linux on MIPS.
278 [John Tobey <jtobey@channel1.com>]
279
280 *) Make links whenever Configure is run, unless we are on Windoze.
281 [Ben Laurie]
282
283 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
284 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
285 in CRLs.
286 [Steve Henson]
287
288 *) Add a useful kludge to allow package maintainers to specify compiler and
289 other platforms details on the command line without having to patch the
290 Configure script everytime: One now can use ``perl Configure
291 <id>:<details>'', i.e. platform ids are allowed to have details appended
292 to them (seperated by colons). This is treated as there would be a static
293 pre-configured entry in Configure's %table under key <id> with value
294 <details> and ``perl Configure <id>'' is called. So, when you want to
295 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
296 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
297 now, which overrides the FreeBSD-elf entry on-the-fly.
298 [Ralf S. Engelschall]
299
300 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
301 [Ben Laurie]
302
303 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
304 on the `perl Configure ...' command line. This way one can compile
305 OpenSSL libraries with Position Independent Code (PIC) which is needed
306 for linking it into DSOs.
307 [Ralf S. Engelschall]
308
309 *) Remarkably, export ciphers were totally broken and no-one had noticed!
310 Fixed.
311 [Ben Laurie]
312
313 *) Cleaned up the LICENSE document: The official contact for any license
314 questions now is the OpenSSL core team under openssl-core@openssl.org.
315 And add a paragraph about the dual-license situation to make sure people
316 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
317 to the OpenSSL toolkit.
318 [Ralf S. Engelschall]
319
320 *) General source tree makefile cleanups: Made `making xxx in yyy...'
321 display consistent in the source tree and replaced `/bin/rm' by `rm'.
322 Additonally cleaned up the `make links' target: Remove unnecessary
323 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
324 to speed processing and no longer clutter the display with confusing
325 stuff. Instead only the actually done links are displayed.
326 [Ralf S. Engelschall]
327
328 *) Permit null encryption ciphersuites, used for authentication only. It used
329 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
330 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
331 encryption.
332 [Ben Laurie]
333
334 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
335 signed attributes when verifying signatures (this would break them),
336 the detached data encoding was wrong and public keys obtained using
337 X509_get_pubkey() weren't freed.
338 [Steve Henson]
339
340 *) Add text documentation for the BUFFER functions. Also added a work around
341 to a Win95 console bug. This was triggered by the password read stuff: the
342 last character typed gets carried over to the next fread(). If you were
343 generating a new cert request using 'req' for example then the last
344 character of the passphrase would be CR which would then enter the first
345 field as blank.
346 [Steve Henson]
347
348 *) Added the new `Includes OpenSSL Cryptography Software' button as
349 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
350 button and can be used by applications based on OpenSSL to show the
351 relationship to the OpenSSL project.
352 [Ralf S. Engelschall]
353
354 *) Remove confusing variables in function signatures in files
355 ssl/ssl_lib.c and ssl/ssl.h.
356 [Lennart Bong <lob@kulthea.stacken.kth.se>]
357
358 *) Don't install bss_file.c under PREFIX/include/
359 [Lennart Bong <lob@kulthea.stacken.kth.se>]
360
361 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
362 functions that return function pointers and has support for NT specific
363 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
364 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
365 unsigned to signed types: this was killing the Win32 compile.
366 [Steve Henson]
367
368 *) Add new certificate file to stack functions,
369 SSL_add_dir_cert_subjects_to_stack() and
370 SSL_add_file_cert_subjects_to_stack(). These largely supplant
371 SSL_load_client_CA_file(), and can be used to add multiple certs easily
372 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
373 This means that Apache-SSL and similar packages don't have to mess around
374 to add as many CAs as they want to the preferred list.
375 [Ben Laurie]
376
377 *) Experiment with doxygen documentation. Currently only partially applied to
378 ssl/ssl_lib.c.
379 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
380 openssl.doxy as the configuration file.
381 [Ben Laurie]
382
383 *) Get rid of remaining C++-style comments which strict C compilers hate.
384 [Ralf S. Engelschall, pointed out by Carlos Amengual]
385
386 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
387 compiled in by default: it has problems with large keys.
388 [Steve Henson]
389
390 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
391 DH private keys and/or callback functions which directly correspond to
392 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
393 is needed for applications which have to configure certificates on a
394 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
395 (e.g. s_server).
396 For the RSA certificate situation is makes no difference, but
397 for the DSA certificate situation this fixes the "no shared cipher"
398 problem where the OpenSSL cipher selection procedure failed because the
399 temporary keys were not overtaken from the context and the API provided
400 no way to reconfigure them.
401 The new functions now let applications reconfigure the stuff and they
402 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
403 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
404 non-public-API function ssl_cert_instantiate() is used as a helper
405 function and also to reduce code redundancy inside ssl_rsa.c.
406 [Ralf S. Engelschall]
407
408 *) Move s_server -dcert and -dkey options out of the undocumented feature
409 area because they are useful for the DSA situation and should be
410 recognized by the users.
411 [Ralf S. Engelschall]
412
413 *) Fix the cipher decision scheme for export ciphers: the export bits are
414 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
415 SSL_EXP_MASK. So, the original variable has to be used instead of the
416 already masked variable.
417 [Richard Levitte <levitte@stacken.kth.se>]
418
419 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
420 [Richard Levitte <levitte@stacken.kth.se>]
421
422 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
423 from `int' to `unsigned int' because it's a length and initialized by
424 EVP_DigestFinal() which expects an `unsigned int *'.
425 [Richard Levitte <levitte@stacken.kth.se>]
426
427 *) Don't hard-code path to Perl interpreter on shebang line of Configure
428 script. Instead use the usual Shell->Perl transition trick.
429 [Ralf S. Engelschall]
430
431 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
432 (in addition to RSA certificates) to match the behaviour of `openssl dsa
433 -noout -modulus' as it's already the case for `openssl rsa -noout
434 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
435 currently the public key is printed (a decision which was already done by
436 `openssl dsa -modulus' in the past) which serves a similar purpose.
437 Additionally the NO_RSA no longer completely removes the whole -modulus
438 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
439 now, too.
440 [Ralf S. Engelschall]
441
442 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
443 BIO. See the source (crypto/evp/bio_ok.c) for more info.
444 [Arne Ansper <arne@ats.cyber.ee>]
445
446 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
447 to be added. Now both 'req' and 'ca' can use new objects defined in the
448 config file.
449 [Steve Henson]
450
451 *) Add cool BIO that does syslog (or event log on NT).
452 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
453
454 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
455 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
456 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
457 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
458 [Ben Laurie]
459
460 *) Add preliminary config info for new extension code.
461 [Steve Henson]
462
463 *) Make RSA_NO_PADDING really use no padding.
464 [Ulf Moeller <ulf@fitug.de>]
465
466 *) Generate errors when private/public key check is done.
467 [Ben Laurie]
468
469 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
470 for some CRL extensions and new objects added.
471 [Steve Henson]
472
473 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
474 key usage extension and fuller support for authority key id.
475 [Steve Henson]
476
477 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
478 padding method for RSA, which is recommended for new applications in PKCS
479 #1 v2.0 (RFC 2437, October 1998).
480 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
481 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
482 against Bleichbacher's attack on RSA.
483 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
484 Ben Laurie]
485
486 *) Updates to the new SSL compression code
487 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
488
489 *) Fix so that the version number in the master secret, when passed
490 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
491 (because the server will not accept higher), that the version number
492 is 0x03,0x01, not 0x03,0x00
493 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
494
495 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
496 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
497 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
498 [Steve Henson]
499
500 *) Support for RAW extensions where an arbitrary extension can be
501 created by including its DER encoding. See apps/openssl.cnf for
502 an example.
503 [Steve Henson]
504
505 *) Make sure latest Perl versions don't interpret some generated C array
506 code as Perl array code in the crypto/err/err_genc.pl script.
507 [Lars Weber <3weber@informatik.uni-hamburg.de>]
508
509 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
510 not many people have the assembler. Various Win32 compilation fixes and
511 update to the INSTALL.W32 file with (hopefully) more accurate Win32
512 build instructions.
513 [Steve Henson]
514
515 *) Modify configure script 'Configure' to automatically create crypto/date.h
516 file under Win32 and also build pem.h from pem.org. New script
517 util/mkfiles.pl to create the MINFO file on environments that can't do a
518 'make files': perl util/mkfiles.pl >MINFO should work.
519 [Steve Henson]
520
521 *) Major rework of DES function declarations, in the pursuit of correctness
522 and purity. As a result, many evil casts evaporated, and some weirdness,
523 too. You may find this causes warnings in your code. Zapping your evil
524 casts will probably fix them. Mostly.
525 [Ben Laurie]
526
527 *) Fix for a typo in asn1.h. Bug fix to object creation script
528 obj_dat.pl. It considered a zero in an object definition to mean
529 "end of object": none of the objects in objects.h have any zeros
530 so it wasn't spotted.
531 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
532
533 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
534 Masking (CBCM). In the absence of test vectors, the best I have been able
535 to do is check that the decrypt undoes the encrypt, so far. Send me test
536 vectors if you have them.
537 [Ben Laurie]
538
539 *) Correct calculation of key length for export ciphers (too much space was
540 allocated for null ciphers). This has not been tested!
541 [Ben Laurie]
542
543 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
544 message is now correct (it understands "crypto" and "ssl" on its
545 command line). There is also now an "update" option. This will update
546 the util/ssleay.num and util/libeay.num files with any new functions.
547 If you do a:
548 perl util/mkdef.pl crypto ssl update
549 it will update them.
550 [Steve Henson]
551
552 *) Overhauled the Perl interface (perl/*):
553 - ported BN stuff to OpenSSL's different BN library
554 - made the perl/ source tree CVS-aware
555 - renamed the package from SSLeay to OpenSSL (the files still contain
556 their history because I've copied them in the repository)
557 - removed obsolete files (the test scripts will be replaced
558 by better Test::Harness variants in the future)
559 [Ralf S. Engelschall]
560
561 *) First cut for a very conservative source tree cleanup:
562 1. merge various obsolete readme texts into doc/ssleay.txt
563 where we collect the old documents and readme texts.
564 2. remove the first part of files where I'm already sure that we no
565 longer need them because of three reasons: either they are just temporary
566 files which were left by Eric or they are preserved original files where
567 I've verified that the diff is also available in the CVS via "cvs diff
568 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
569 the crypto/md/ stuff).
570 [Ralf S. Engelschall]
571
572 *) More extension code. Incomplete support for subject and issuer alt
573 name, issuer and authority key id. Change the i2v function parameters
574 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
575 what that's for :-) Fix to ASN1 macro which messed up
576 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
577 [Steve Henson]
578
579 *) Preliminary support for ENUMERATED type. This is largely copied from the
580 INTEGER code.
581 [Steve Henson]
582
583 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
584 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
585
586 *) Make sure `make rehash' target really finds the `openssl' program.
587 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
588
589 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
590 like to hear about it if this slows down other processors.
591 [Ben Laurie]
592
593 *) Add CygWin32 platform information to Configure script.
594 [Alan Batie <batie@aahz.jf.intel.com>]
595
596 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
597 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
598
599 *) New program nseq to manipulate netscape certificate sequences
600 [Steve Henson]
601
602 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
603 few typos.
604 [Steve Henson]
605
606 *) Fixes to BN code. Previously the default was to define BN_RECURSION
607 but the BN code had some problems that would cause failures when
608 doing certificate verification and some other functions.
609 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
610
611 *) Add ASN1 and PEM code to support netscape certificate sequences.
612 [Steve Henson]
613
614 *) Add ASN1 and PEM code to support netscape certificate sequences.
615 [Steve Henson]
616
617 *) Add several PKIX and private extended key usage OIDs.
618 [Steve Henson]
619
620 *) Modify the 'ca' program to handle the new extension code. Modify
621 openssl.cnf for new extension format, add comments.
622 [Steve Henson]
623
624 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
625 and add a sample to openssl.cnf so req -x509 now adds appropriate
626 CA extensions.
627 [Steve Henson]
628
629 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
630 error code, add initial support to X509_print() and x509 application.
631 [Steve Henson]
632
633 *) Takes a deep breath and start addding X509 V3 extension support code. Add
634 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
635 stuff is currently isolated and isn't even compiled yet.
636 [Steve Henson]
637
638 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
639 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
640 Removed the versions check from X509 routines when loading extensions:
641 this allows certain broken certificates that don't set the version
642 properly to be processed.
643 [Steve Henson]
644
645 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
646 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
647 can still be regenerated with "make depend".
648 [Ben Laurie]
649
650 *) Spelling mistake in C version of CAST-128.
651 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
652
653 *) Changes to the error generation code. The perl script err-code.pl
654 now reads in the old error codes and retains the old numbers, only
655 adding new ones if necessary. It also only changes the .err files if new
656 codes are added. The makefiles have been modified to only insert errors
657 when needed (to avoid needlessly modifying header files). This is done
658 by only inserting errors if the .err file is newer than the auto generated
659 C file. To rebuild all the error codes from scratch (the old behaviour)
660 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
661 or delete all the .err files.
662 [Steve Henson]
663
664 *) CAST-128 was incorrectly implemented for short keys. The C version has
665 been fixed, but is untested. The assembler versions are also fixed, but
666 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
667 to regenerate it if needed.
668 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
669 Hagino <itojun@kame.net>]
670
671 *) File was opened incorrectly in randfile.c.
672 [Ulf Möller <ulf@fitug.de>]
673
674 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
675 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
676 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
677 al: it's just almost always a UTCTime. Note this patch adds new error
678 codes so do a "make errors" if there are problems.
679 [Steve Henson]
680
681 *) Correct Linux 1 recognition in config.
682 [Ulf Möller <ulf@fitug.de>]
683
684 *) Remove pointless MD5 hash when using DSA keys in ca.
685 [Anonymous <nobody@replay.com>]
686
687 *) Generate an error if given an empty string as a cert directory. Also
688 generate an error if handed NULL (previously returned 0 to indicate an
689 error, but didn't set one).
690 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
691
692 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
693 [Ben Laurie]
694
695 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
696 parameters. This was causing a warning which killed off the Win32 compile.
697 [Steve Henson]
698
699 *) Remove C++ style comments from crypto/bn/bn_local.h.
700 [Neil Costigan <neil.costigan@celocom.com>]
701
702 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
703 based on a text string, looking up short and long names and finally
704 "dot" format. The "dot" format stuff didn't work. Added new function
705 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
706 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
707 OID is not part of the table.
708 [Steve Henson]
709
710 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
711 X509_LOOKUP_by_alias().
712 [Ben Laurie]
713
714 *) Sort openssl functions by name.
715 [Ben Laurie]
716
717 *) Get the gendsa program working (hopefully) and add it to app list. Remove
718 encryption from sample DSA keys (in case anyone is interested the password
719 was "1234").
720 [Steve Henson]
721
722 *) Make _all_ *_free functions accept a NULL pointer.
723 [Frans Heymans <fheymans@isaserver.be>]
724
725 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
726 NULL pointers.
727 [Anonymous <nobody@replay.com>]
728
729 *) s_server should send the CAfile as acceptable CAs, not its own cert.
730 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
731
732 *) Don't blow it for numeric -newkey arguments to apps/req.
733 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
734
735 *) Temp key "for export" tests were wrong in s3_srvr.c.
736 [Anonymous <nobody@replay.com>]
737
738 *) Add prototype for temp key callback functions
739 SSL_CTX_set_tmp_{rsa,dh}_callback().
740 [Ben Laurie]
741
742 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
743 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
744 [Steve Henson]
745
746 *) X509_name_add_entry() freed the wrong thing after an error.
747 [Arne Ansper <arne@ats.cyber.ee>]
748
749 *) rsa_eay.c would attempt to free a NULL context.
750 [Arne Ansper <arne@ats.cyber.ee>]
751
752 *) BIO_s_socket() had a broken should_retry() on Windoze.
753 [Arne Ansper <arne@ats.cyber.ee>]
754
755 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
756 [Arne Ansper <arne@ats.cyber.ee>]
757
758 *) Make sure the already existing X509_STORE->depth variable is initialized
759 in X509_STORE_new(), but document the fact that this variable is still
760 unused in the certificate verification process.
761 [Ralf S. Engelschall]
762
763 *) Fix the various library and apps files to free up pkeys obtained from
764 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
765 [Steve Henson]
766
767 *) Fix reference counting in X509_PUBKEY_get(). This makes
768 demos/maurice/example2.c work, amongst others, probably.
769 [Steve Henson and Ben Laurie]
770
771 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
772 `openssl' and second, the shortcut symlinks for the `openssl <command>'
773 are no longer created. This way we have a single and consistent command
774 line interface `openssl <command>', similar to `cvs <command>'.
775 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
776
777 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
778 BIT STRING wrapper always have zero unused bits.
779 [Steve Henson]
780
781 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
782 [Steve Henson]
783
784 *) Make the top-level INSTALL documentation easier to understand.
785 [Paul Sutton]
786
787 *) Makefiles updated to exit if an error occurs in a sub-directory
788 make (including if user presses ^C) [Paul Sutton]
789
790 *) Make Montgomery context stuff explicit in RSA data structure.
791 [Ben Laurie]
792
793 *) Fix build order of pem and err to allow for generated pem.h.
794 [Ben Laurie]
795
796 *) Fix renumbering bug in X509_NAME_delete_entry().
797 [Ben Laurie]
798
799 *) Enhanced the err-ins.pl script so it makes the error library number
800 global and can add a library name. This is needed for external ASN1 and
801 other error libraries.
802 [Steve Henson]
803
804 *) Fixed sk_insert which never worked properly.
805 [Steve Henson]
806
807 *) Fix ASN1 macros so they can handle indefinite length construted
808 EXPLICIT tags. Some non standard certificates use these: they can now
809 be read in.
810 [Steve Henson]
811
812 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
813 into a single doc/ssleay.txt bundle. This way the information is still
814 preserved but no longer messes up this directory. Now it's new room for
815 the new set of documenation files.
816 [Ralf S. Engelschall]
817
818 *) SETs were incorrectly DER encoded. This was a major pain, because they
819 shared code with SEQUENCEs, which aren't coded the same. This means that
820 almost everything to do with SETs or SEQUENCEs has either changed name or
821 number of arguments.
822 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
823
824 *) Fix test data to work with the above.
825 [Ben Laurie]
826
827 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
828 was already fixed by Eric for 0.9.1 it seems.
829 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
830
831 *) Autodetect FreeBSD3.
832 [Ben Laurie]
833
834 *) Fix various bugs in Configure. This affects the following platforms:
835 nextstep
836 ncr-scde
837 unixware-2.0
838 unixware-2.0-pentium
839 sco5-cc.
840 [Ben Laurie]
841
842 *) Eliminate generated files from CVS. Reorder tests to regenerate files
843 before they are needed.
844 [Ben Laurie]
845
846 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
847 [Ben Laurie]
848
849 Changes between 0.9.1b and 0.9.1c
850
851 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
852 changed SSLeay to OpenSSL in version strings.
853 [Ralf S. Engelschall]
854
855 *) Some fixups to the top-level documents.
856 [Paul Sutton]
857
858 *) Fixed the nasty bug where rsaref.h was not found under compile-time
859 because the symlink to include/ was missing.
860 [Ralf S. Engelschall]
861
862 *) Incorporated the popular no-RSA/DSA-only patches
863 which allow to compile a RSA-free SSLeay.
864 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
865
866 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
867 when "ssleay" is still not found.
868 [Ralf S. Engelschall]
869
870 *) Added more platforms to Configure: Cray T3E, HPUX 11,
871 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
872
873 *) Updated the README file.
874 [Ralf S. Engelschall]
875
876 *) Added various .cvsignore files in the CVS repository subdirs
877 to make a "cvs update" really silent.
878 [Ralf S. Engelschall]
879
880 *) Recompiled the error-definition header files and added
881 missing symbols to the Win32 linker tables.
882 [Ralf S. Engelschall]
883
884 *) Cleaned up the top-level documents;
885 o new files: CHANGES and LICENSE
886 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
887 o merged COPYRIGHT into LICENSE
888 o removed obsolete TODO file
889 o renamed MICROSOFT to INSTALL.W32
890 [Ralf S. Engelschall]
891
892 *) Removed dummy files from the 0.9.1b source tree:
893 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
894 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
895 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
896 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
897 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
898 [Ralf S. Engelschall]
899
900 *) Added various platform portability fixes.
901 [Mark J. Cox]
902
903 *) The Genesis of the OpenSSL rpject:
904 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
905 Young and Tim J. Hudson created while they were working for C2Net until
906 summer 1998.
907 [The OpenSSL Project]
908
909 Changes between 0.9.0b and 0.9.1b
910
911 *) Updated a few CA certificates under certs/
912 [Eric A. Young]
913
914 *) Changed some BIGNUM api stuff.
915 [Eric A. Young]
916
917 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
918 DGUX x86, Linux Alpha, etc.
919 [Eric A. Young]
920
921 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
922 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
923 available).
924 [Eric A. Young]
925
926 *) Add -strparse option to asn1pars program which parses nested
927 binary structures
928 [Dr Stephen Henson <shenson@bigfoot.com>]
929
930 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
931 [Eric A. Young]
932
933 *) DSA fix for "ca" program.
934 [Eric A. Young]
935
936 *) Added "-genkey" option to "dsaparam" program.
937 [Eric A. Young]
938
939 *) Added RIPE MD160 (rmd160) message digest.
940 [Eric A. Young]
941
942 *) Added -a (all) option to "ssleay version" command.
943 [Eric A. Young]
944
945 *) Added PLATFORM define which is the id given to Configure.
946 [Eric A. Young]
947
948 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
949 [Eric A. Young]
950
951 *) Extended the ASN.1 parser routines.
952 [Eric A. Young]
953
954 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
955 [Eric A. Young]
956
957 *) Added a BN_CTX to the BN library.
958 [Eric A. Young]
959
960 *) Fixed the weak key values in DES library
961 [Eric A. Young]
962
963 *) Changed API in EVP library for cipher aliases.
964 [Eric A. Young]
965
966 *) Added support for RC2/64bit cipher.
967 [Eric A. Young]
968
969 *) Converted the lhash library to the crypto/mem.c functions.
970 [Eric A. Young]
971
972 *) Added more recognized ASN.1 object ids.
973 [Eric A. Young]
974
975 *) Added more RSA padding checks for SSL/TLS.
976 [Eric A. Young]
977
978 *) Added BIO proxy/filter functionality.
979 [Eric A. Young]
980
981 *) Added extra_certs to SSL_CTX which can be used
982 send extra CA certificates to the client in the CA cert chain sending
983 process. It can be configured with SSL_CTX_add_extra_chain_cert().
984 [Eric A. Young]
985
986 *) Now Fortezza is denied in the authentication phase because
987 this is key exchange mechanism is not supported by SSLeay at all.
988 [Eric A. Young]
989
990 *) Additional PKCS1 checks.
991 [Eric A. Young]
992
993 *) Support the string "TLSv1" for all TLS v1 ciphers.
994 [Eric A. Young]
995
996 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
997 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
998 [Eric A. Young]
999
1000 *) Fixed a few memory leaks.
1001 [Eric A. Young]
1002
1003 *) Fixed various code and comment typos.
1004 [Eric A. Young]
1005
1006 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1007 bytes sent in the client random.
1008 [Edward Bishop <ebishop@spyglass.com>]
1009
